DEF / AdBlue level sensor hub
SCR tank level sensors only: AdBlue, DEF, urea and reductant applications
Use this page for SCR tank level-temperature modules, quality-level headers and reductant sender units. General coolant, washer, fuel, oil and industrial fluid sensors are intentionally separated.
Included scope
- AdBlue / DEF / urea / reductant tank level sensors
- SCR tank level-temperature modules and quality-level headers
- OE/photo confirmation for commercial vehicle and off-highway applications
Separated scope
- Coolant, washer fluid, fuel, oil and hydraulic tank sensors
- BEDIA, marine, industrial and general reed-switch level sensors
SCR tank level sensors only: AdBlue, DEF, urea, reductant level and quality monitoring.
This page is dedicated to diesel exhaust fluid tank sensors used in SCR systems. It covers AdBlue / DEF / urea level sensors, level-temperature sensors, quality-level headers, and reductant tank sender units for trucks, buses, off-highway equipment, and commercial vehicles.
Page scope
- Included here: AdBlue, DEF, urea, reductant tank level sensors.
- Included here: SCR tank level-temperature modules and quality-level headers.
- Not included here: coolant, washer fluid, oil, fuel, BEDIA industrial, marine, and general reed-switch fluid sensors.
Coolant, washer fluid, oil, fuel, industrial and marine level sensors are organized separately.

AdBlue / DEF fitment details to confirm
- OE / OEM reference number and truck or equipment application
- Tank depth, flange shape, connector type, and cable orientation
- Level-only, level-temperature, or level-quality header function
- Heater requirement and SCR system generation, such as Euro 5, Euro 6, Tier 4, or China VI
For SCR tank sensors, small differences in tank depth, connector and header shape can change compatibility. Send the OE number, label photo, or installed sensor photo before bulk ordering.

Buyer FAQ
Why does tank depth matter for AdBlue level sensors?
Different tank modules can share similar connectors but use different length, heating, and sensing configurations.
Can SHR Autoparts check AdBlue level sensor compatibility?
Yes. Send the module label, connector photo, and vehicle application for cross-reference support.
